wikipedia says scrubs can have trees up to 8m while heath they limit to 2,
but actually they divide scrubs into 8 subtypes, two of them heaths:

http://en.wikipedia.org/wiki/Scrubland

For shrubs 2–8 m high the following structural forms result:

   - dense foliage cover (70–100%) — *closed-scrub*
   - mid-dense foliage cover (30–70%) — *open-scrub*
   - sparse foliage cover (10–30%) — *tall shrubland*
   - very sparse foliage cover (<10%) — *tall open shrubland*

For shrubs <2 m high the following structural forms result:

   - dense foliage cover (70–100%) —
*closed-heath<http://en.wikipedia.org/wiki/Heath_%28habitat%29>
   *
   - mid-dense foliage cover (30–70%) — *open-heath*
   - sparse foliage cover (10–30%) — *low shrubland*
   - very sparse foliage cover (<10%) — *low open shrubland*
